“Even now when I listen to them, some of the guitar is so out of tune it’s unbelievable. I couldn’t believe that here they were in this high-tech age, with four-track recording machines, and they couldn’t go back and do it with a tuned guitar. Being out of tune… I find it unforgivable, really. Which songs? I can’t remember, but it’s mostly their guitar solos, which can be fairly horrific.”
